Varicella, i.e. chickenpox, is uncommon in adult age because this highly contagious primary infection by Varicella zoster virus mainly affects children before the age of 10 years. The lesions are in different phases of development: vesicles surrounded by red halo, drying, often necrotic vesicles, crusts or initial red lesions without vesicles. General symptoms with high fever are typical for chickenpox in the adult age.
